Percent increase = (new number - original number) / original number...* 100
= (42 - 20) / 20....* 100
= 22/20 * 100
= 1.1 * 100
= 110 % increase
Answer:
43.3
Step-by-step explanation:
45-5=40,
0.0825*40=3.3
40+3.3=43.3
Answer:
The area of the pentagon is approximately 193 square inches.
Step-by-step explanation:
In order to solve this problem we need to apply the appropriate formula to calculate the area of the pentagon. This formula is shown below:
area = (perimeter*apothem)/2
Applying the data from the problem, we have:
area = (53*7.3)/2
area = 386.9/2
area = 193.45 square inches
The nearest whole number is 193 square inches.
Step-by-step explanation:
such a rectangular prism is in that sense like a cube (or die) : it has 6 sides or surface areas. top, down, front, back, left, right.
to get the total surface area we need to calculate each individual side area and sum all 6 of them up.
since it is a rectangular shape, there are 3 pairs of equal side areas, so, we really need to calculate only 3 different ones :
front and back : each is
10×9 = 90 in², both together are 180 in²
left and right : each is
8×9 = 72 in², both together are 144 in²
top and bottom : each is
10×8 = 80 in², both together are 160 in²
the total surface area of the prism is
180 + 144 + 160 = 484 in²
5/7 +1/7
=6/7 , is the answer
